Air Suspension Indicator (if equipped)
WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The air suspension indicator is hardwired to the instrument cluster. If a air suspension malfunction occurs, the air suspension switch closes to ground, illuminating the air suspension indicator. The air suspension indicator also is illuminated with ignition key in the RUN position and if the air suspension service switch is off.
